Welcome, James. You definitely came to the right site for helpful advice. There are many members here that own 105Es includes myself.
Please continue posting pictures on your restoration progress. Pete

If you have an original wheel to the car,
it'll have a month/year code stamped on one of the
ears that hold the hubcaps on.Mine's stamped 4/60.
Many of these were registered as to when
they were sold.A '60 could be registered as a '61.
This was pretty common back then._________________Remember - Nobody EVER says "COOL PRIUS!"
